FILLING DEVICE FOR BATTERIES AND THE LIKE.

a ueanoa filed March 5, 1921. Serial no. 449,675.

To all whom it may concern Be. it known that I, Or'ro H. Korea, acitizen of the United States. residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in a Filling Device for Batteries and the like, ofwhich the following is a specification.

My invention relates to a filling device for batteries and the like, andmy invention particularly relates to improvements in filling devicesused for filling storage batteries with water in sufiicient quantity tobring the normal water level to the proper height. above the plateswithin the battery.

The object of my invention is to provide a device having a liquidcontainer which may be placed in an inverted position, resting upon thebattery, having flexible tubes extending a predetermined length intothev battery, which tubes will not injure the battery plates, as theweight of the container rests upon the top of the battery and not uponthe plates; a further object of my invention is to provide means forshutting off the flow of water through the tube from the containerduring the placing of the container into position upon the battery andalso when removing the same from the battery, whereby water will not bespilled over the top of the battery, and a still further object of myinvention is to provide a device which is simple in construction andoperation, and which can be manufactured at a low cost.

Referring to the accompanying drawing, Fig. 1, is a perspective view ofmyimproved filling device; Fig. 2, is a side elevation of the fillingdevice secured in a container and shown in the inverted position restingupon a battery, partlyshown in section; Fig.3, is a transverse sectionon line 33 Fig. 2; Fig. 4, is a vertical section on line 44 Fig. 3; Fig.5, is a side elevation of a different form of stopper having fingerrecesses formed on opposite sides thereof for impinging the tubes, andFig. 6 is a transverse section on line 6-6 Fig. 5.

In the accompanying drawings, in which like reference characters referto like parts; 1 represents the stopper having a body portion 2 adaptedto be tightly fitted into the mouth 3 of a container 4. The stopper 7 isprovided with a head portion 6 connected with the body portion ,2 by aconnecting member 7 which latter is a suflicient length to permit thestopper having a recess 9,

mensions so that a finger may be placed therein and compress either ofthe tubes 12 and 13 extending longitudinally through the stopper.

The tubes 12 and 13 are sealed, or tightly fitted, into the aperturesformed through the body portion 2 of the stopper, to prevent airentering the container 4 around said tubes.

The connecting member 7 of the stopper is provided with a lug 15positioned opposite to'the finger recess 9. Said lug 15 forms a ridgeover which the tubes are slightly curved, as shown in Fig. 4, andagainst which the tubes may be more readily compressed by the finger toclose the passageway through the tubes and thus shut ofi the flow of airor liquid through the same.

The head portion 6 of the stopper is adapted to rest upon the flange 16formed on the top of the storage battery 17, and support the container 4in an inverted posi- .tion with the ends of the tubes 12 and 13extending through'the filling opening 18 of the battery. The end surfaceof the head 6 is provided with radial grooves 20 to allow air to passbetween the head and the battery flange 16.

The water tube 13. is out off the proper length beyond the head 6, sothat the end of said tube will just touch the plates 22 of the batteryand the air tube 12 is then cut as much shorter than the water tube 13as it is desired to have the water level normally maintained above theplates.

Figs. 5 and 6, show a modified form of the stopper in which recesses 25and 26 are formed opposite each other and extending through the stopper,exposing the tubes from either side of the stopper, thus permitting' thetubes to be compressed between two fingers, which may readily beinserted ger is placed up one or both of the tubes to shut off the flowof air or water through the tubes and the receptacle can then beinverted and placed on the top of the battery with-the tubes extendinginto thefilling opening; the finger is then removed and air enters thereceptacle from the battery through the shortertube which permits thewater to flow through the longer tube until the level of the liquid inthe battery seals the mouth of the air tube. The fingers are againplaced upon the tubes to prevent the water from dripping over thebattery when the container is being removed from the battery. 7

Having thus described my invention I claim and desire to secure byLetters Patent:

1. A filling device comprising a stopper having a body portion, a headportion, a connecting member between the body portion and the headportion, flexible tubes extending through the said body portion and thehead portion and projecting-predetermined leng'ths'beyond the headportion, whereby the head portion will limit the distance the tubes maybe inserted into a receptacle, and said connecting member beingconstructed to permit the tubes ,to be compressed between the said bodyand head portions. 2. A battery fillin device comprising a stopperadapted to efitted intoa liquid container, said stopper having a portionthereon adapted to rest upon a battery adj ac'ent to the fillingaperture formed therein, a tube extending through the stopper for thepassageof air into the container and adapted to extend into the batteryaperture and terminate at the normal liquid level of the battery, asecond tube extending through the stopper for the passage of liquid intothe battery and terminating below the said normal liquid level, and saidlast mentioned tube being made of flexible material so as not to injurethe interior of the battery. o

3. A battery filling device comprising a stopper adapted to be fittedinto a container, tubes extending through the stopper for the passage ofair and liquid and adapted to be inserted into the filling aperture of abattery, said stopper having a portion adapted to rest'upon the outsideof the battery to limit the distance the said tubes may be inserted intothe battery and said tubes being niade of flexible material so as not toinjure the battery plates.

4. A filling device comprising a container for holding a supply ofliquid, tubes for the passage of air and liquid to and from thecontainer, a member upon the container located adjacent to the saidtubes forming a rest for supporting the container upon the top of areceptacle having a filling aperture formed therein, said tubesextending 'a predetermined length beyond the support ing surface of thesaid rest member to limit the distance the tubes may extend through thesaid aperture into the receptacle, and said member having an openportion formed therein exposing a portion of the tubes whereby the tubesmay be compressed at a point between the container and the rest end ofthe said member to shut 0d the flow of liquid.

In'testimony whereof I aflix my signature.

OTTO H. KOLB.
